Blog questions from a total noob

So I have used both VSD and RSD and done a few websites, but I am a total non-coding, know-enough-to-be-dangerous kinda user. Blogs are a puzzle to me, and I need to gleam the vast knowledge of The Forums. I did a search and didn't find any answers, so forgive me if this is an already discussed topic!

I want a blog to share travels with friends and family. Not looking to make money or anything, just share info. I don't want to add it to my website, since it has nothing to do with my business. Is a "just a blog" a different animal? Do you create just a blog? Or do you create a webpage and insert a blog? I already have my site on S-drive, but don't know how to get it set up for a blog. Looked into stream, but again, not sure how to take the first step.
